It happened a few times that when I want to download a new map or any other mod through Mediafire my PC makes a beep and this screen pops up.
As you can see in the screenshot below it seems to be quite harmless but I don't like this kind of warnings.
Or is it just false alarm and can I ignore it?
Any help from an expert here would be very much appreciated...

I am also getting that warning from no reason. I am using Avira on Gaming Rig.
